Long regarded one of the bluest lilacs, Syringa vulgaris 'President Lincoln' is an upright, deciduous shrub with large, showy panicles packed with wonderfully fragrant, single, lavender-blue flowers. Blooming in late spring, this is a fast-growing, leafy lilac with open branches clothed in light green, heart-shaped leaves that remain attractive in summer, but may tend to hide the flowers. Introduced in 1916, this old cultivar remains as popular as ever. To extend the season of interest of your lilac, grow clematis with different bloom times through its branches to add color and glamour to the shrub. Perfect for sunny mixed borders. Named in honor of Abraham Lincoln, the 16th president of the United States of America.
- Grows with a relatively loose habit, up to 8-10 ft. tall and wide (240-300 cm).
- A full sun lover, this plant is easily grown in fertile, humus-rich, alkaline to neutral, dry to medium, well-drained soils. Thrives in chalk but dislikes acidic soils. Tolerates light shade, but the best flower production occurs in full sun. Appreciates mulching when planted in full sun. Needs good air circulation.
- No serious insect or disease problems. May get leaf-mining moths, thrips or be affected by lilac blight
- Attracts butterflies and hummingbirds but is deer resistant.
- Plant as a specimen or massed in mixed shrub borders for dramatic spring blooms. Use it in the perennial border to add structure to a bed. Great flowering shrub that is perfect for flowering hedges or foundation plantings.
- Propagate by softwood cuttings or layering in early summer. Grafting can be done in winter and chip budding in summer.
- Prune immediately after flowering. Prompt removal of faded flowers before seed set will increase the bloom production in the following year. Promptly remove root suckers to maintain a neat appearance and prevent unwanted colonial spread.
